To all 'zlfLo/n. it muy concern.' y

Be it known that I, WILLIAM BARTHOLO- Mnw, a citizen of the United States, residing at Chicago. county of Cook, Stateof Illiuois` have invented certain new and useful linprovenients` in Mangles, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a mangle or ironing machine for flat work `and particularly to means for controlling the driving mechanisms and lifting the rolls from their cooperating steam chests, and is a companion case of my application filed October 2S, 1912, for stop mechanism, Serial N1unbei 728,312.

The invention has for an object to provide a novel and improved construction of lifting mechanism for separating the clothed rolls -from the cooperating steam chests.

Another object of the invention is to provide a novel and improved construction of guard board and connections mounted to cooperate with a tripping device whereby the operation of the machine may be stopped, together with means for resetting or starting the machine after having been so tripped.

A further object of the invention is to provide a novel and improved construction of 4safety device adapted to stop the operation of the machine and arranged to Operate the raising mechanism for the rolls.

Other and further Objects and advantages Vof the invention will be hereinafter set forth and 4the novel features thereof defined by the appended claims.

In the drawings- Figure 1 is a side elevation of the mangle; Fig. 2 is a detail side elevation of the opposite side of the machine at the feed end thereof; Fig. 3 is a top plan of the roll raising mechanism; Fig. 4 is a front elevation of this mechanism; Fig. 5 is a central horizontal section through the roll raising means; Fig. 6 is an end elevation thereof looking from the left of Fig. 4; Fig. 7 isa detail section showing means for retaining the hand lever in position: Fig. 8 isa side elevation of the safety device by which the driving power is disconnected; Fig. 9 is a vertical section on line 9 9 of Fig. 8; Fig. 10 is a horizontal section on line 10 -1O of Fig. 8;- Fig. 11 is a similar section on line 11--11 of Fig.

a six roll flat work ironer, in which the usual clothed rolls 20 are adapted to coperate with the steam chests 21 as indicated by dotted lines in Fig. 1. These rolls may be driven in any desired manner, for instance from a power shaft 22 provided with a pinion 23 which meshes with driving gears 24 mounted upon the shafts 25, which shafts also carry pinlons 26 disposed in driving relation to gears 27 upon the rolls by which the latter are rotated in the same direction andin the usual manner. in the art. The rolls 20 are mounted in a movable frame 28 disposed at the upper face of the main frame 29 of the machine. and this movable frame is adapted to be shifted to raise the rolls from the steam chests by means of the longitudinally extending rod 30, as shown by dotted lines in Fig. 1. This rod is connected by pivoted links 31 with the movable frame 28 and by means of similar links 32 with the main frame 29. Oneof the links 32 is provided with a bellcrank arm 33 from which a lifting rod 34 extends down'- ward. A,

At the feed end of the mangle, the usual feed apron 35 is provided and adapted to Ibe driven throughv the chain and sprocketv connections 36 as shown in Fig; 1. These may comprise a sprocket 37 upon the shaft of the feed apron roller over which 4the chain 36 extends and is guided by the idlersl 88 to the sprocket 39 disposed upon. a shaft driven by geared connections 40 from the roll-rotatingmeans.y Above the feed apron 35, a-inger or guard boardr41 is mounted by means of the brackets 42 as will be hereinafter described. At the delivery end of `the machine, a belt or apron bracket 43 is pivotally mounted at 44 and carries the apron 45 which contacts with the under faceof lthe chests to effecta 'drying and ironing action' during the return of the goods toward thefeed end ofthe mangle in the manner usual-in this art. The goods which is Y provided with a hand wheel 68 by TFig. 1.

are again returned toward the delivery end ot the machine by means lof the return apron 46 which cooperates with the under tace of the lower ply of the apron and extends to the apron bracket 43 where the ironcd article is delivered. This bracket is adapted to be swung away from the unal roll and steam chest so as to remove the upper ply ot the apron 45 from contact with the under face of the'chests by means of a bell crank lever 47 pivot/ed to the main Jframe at 48 and pivot-ally connected to the rod 30 by which the roll carrying frame is lifted. This lever 47 has a link 49 pivotally connected thereto and 'to the bracket 43. llor the purpose of `cushioning the movement ot this bracket and retaining it in position under proper tension, a rod 50 is extended downward therefrom and passes through a guide 51 upon the frame 29. This rod is surrounded by a tension spring l which bears against the guide at its? lower end and contacts with an adjustable collar 53 secured to the rod at its upperi end.

The roll lifting rod 34v is provided at its lower end with a cam sleeve 54 adapted to embrace a cam 55 disposed upon the shaft 56 which is also provided with a sector 57 meshing with a worm 58 upon thecountershaft 59, as shown in Figs. 3, 4, 5 and 6. The countershalt'59 is provided at one end with a beveled gear 69 meshing' with a cooperating gear 61 carried by the shalt 62 which the rolls may be raised or lowered by hand when desired or it the power connections are disconnected. The opposite end ot the countershatt 59 is provided with a beveled gear 64 which meshes with the oppositely disposed beveled gears 65 and 66 which are loosely mounted. upon the shaft 67 provided with a driving sprocket 68. Slidingly secured upon the shaft 67 is a clutch member 69 provided at its o posite sides with the clutch faces 70 adapte to cooperate with the clutch member 71 carried by the beveled gears 65 and 66. The shaft 67 is adapted to be driven from the power shaft 22 yby means of the chain 72 extending to the sprocket 73 upon the shaft '74.V rThis shaft also carries a sprocket 75 trom which a driving chain 76 extends to the sprocket 68 upon the shaft 67 as shown in For the purpose of shitting the clutch 69 toa neutral or nonoperative position when the rolls reach the limit of their movement either toward or from the chests, a shitting lever 77 is pivotally mounted at 7 8 upon the supporting bracket 79 and has a bilurcated portion embracing; the clutch 69 in the usual manner. This lever is provided with a lateral crank arm 80 having at its outer end a sleeve 81 mounted to slide upon a dependi shaft 85.

ing rod 82 which is secured to the rod d4 by a bracket 88. The lower end o this rod is threaded and provided with adjustable stop nuts 84 thereon at opposite sides ot the sleeve 81. llt will be seen that in the reciprocation ot the rod 34, the stop nuts will engage the crank arm 80 and operate the clutch member automatically when the proper travel has been secured.

Under some conditions, it is desirable to shift the clutch manually to actuate the rod 34 in eitherv direction or entirely disconnect the power therefrom. This may be conveniently accomplished by means ot a roel: shaft 85 mounted in bearings 86 upon the main frame and provided with an operating lever 87 as shown in Figs. 3 and 4. The shaft 85 isprovided with a crank arm 88 which., at its outer'end, is formed with a slotted connection 89 with a lever 90 pivoted at 91. The lower end of this lever is provided vvith a pin working in a slotted connection 92 in the clutch lever 7 7 in order to shift the latter by the oscillation of the rock For the purpose oi retaining or holding the rock shaft 85 in its adjusted position, a holding sector 93 is adjustably secured thereon and provided upon its curved outer tace with a lug or projection 94 adapted to seat between the ends oil the looped spring 95 secured upon a hired part 96. By this means, the shaft and its operating lever may be securely retained in position to render the clutch inoperative.

- The guard board 41 is pivoted at 100 upon the bracket 42 and provided with a crank arm 101 from which a trip rod 102 extends to a lever arm 103 on shaft 197. The shaft 107 is provided with a biturcated crank arm 110 adapted to actuate an auxiliary clutch 111 slidably mounted upon the shaft 112. This shaft and the other members ot the satety device for disconnecting the power are supported at their outer ends in the bearing bracket 113. The shaft 112 is provided with a loosely mounted pinion 114 thereon provided with a clutch member 115 to cooperate with theclutch 111. The hub et the pinion 114 is provided with a beveled gear 116 which meshes with a cooperating gear 117 mounted upon the shatt 118. The hub ot the gear 117 has secured thereon an eccentric 119 which is adapted to travel in contact with a shitting lever 120 pivoted at its lower end 121 to the bracket 113 and biturcated at its upper end 122 to embrace a clutch member 123 which is slidingly keyed upon the power shaft 22 and cooperates with a clutch member 124 carried by the pinion 125 loose' upon the power shalt. The clutch members 123 and 124 are normally held in engagement by the spring 126 surrounding the power shaft and bearing upon the clutch 123 at one end and at its opposite end against the bearing boa 127 oit the bracket 4, mennen reciprocating said rod., means for actuating said lifting rod, and means carried by said lifting rod tor controllingn the actuating steam chest. a coperating roll supporting` frame, a lillting rod carried by said traine, means Jfor actuating said rod, a clutch connection for actuating said lifting rod, e. depending arin troni said rod, a bell crank lever pivoted to a snp-porting' bracket, stops carried b v said arm to engage said lever, a rock shaft. provided with an operating liandle, a lever arm carried by Said shaft, and a. lever connected to. said arm and to said bell crank lever.
